When my DT get's into 5th and 6th it starts to lose power and struggles to pick up revs, does anyone have any ideas why?
Is the bike modified?
Always Originate, Never Pirate!
@Calum it has a giannelli down pipe and dep sport end can
@Blaze-Vile and the jetting is standard
I believe so, what size jet would i need ?
@Blaze-Vile 210 Stock main jet.
To be fair, I would have to refer to the manual to know.
Is the bike still restricted? The 2001-04 models were the worst for restrictions.
Reed Valve, CDI, Exhaust.
The bike is no longer restricted

This is all the manual says about jets and reed valves
@Blaze-Vile Sounds like it could be an electrical fault.
Check CDI, Coil, Spark Plug, HT Lead etc.
Air box isn't restricted. Air filter clean from debris etc?
